Background

Stroke remains a leading cause of death and disability worldwide, but outcomes are far from uniform across patient populations. Traditional stroke research has predominantly centered on generalized mechanisms and treatment strategies. However, mounting evidence highlights that anatomical heterogeneity, sex-linked biological differences, and age-dependent physiological variations critically influence stroke onset, severity, therapeutic responsiveness, and recovery. Recent advances in neuroimaging, molecular biology, and precision medicine now allow us to disentangle these dimensions with greater clarity. For instance, structural vascular variability can alter collateral flow and infarct progression; hormonal influences and chromosomal differences underlie divergent stroke phenotypes between men and women; and age shapes neurovascular resilience, neuroplasticity, and responses to pharmacological or interventional therapies. A systematic exploration of these factors is urgently needed to improve risk stratification, optimize individualized treatment, and design more inclusive clinical trials. This special thematic issue aims to unify current knowledge, stimulate debate, and foster translational approaches that acknowledge patient diversity in stroke care.

We invite submissions that span the spectrum of basic, translational, and clinical research, with emphasis on how anatomical, sex-based, and age-specific factors intersect to shape stroke pathophysiology and therapy. Contributions may include original research, reviews, meta-analyses, clinical trial reports, technical advances, and perspective articles.

Key themes include:

1. Anatomical Variability in Stroke
 Cerebral vascular variants (circle of Willis morphology, collateral pathways, vascular tortuosity) and their impact on ischemic vulnerability
 Neuroimaging biomarkers capturing individual variability in perfusion and tissue viability. Implications of vascular anatomy for endovascular procedures and surgical outcomes.

2. Sex-Based Differences
 Hormonal modulation of stroke risk, progression, and recovery.
 Sex-specific inflammatory and immune responses following ischemia or hemorrhage.
 Gender disparities in clinical trial representation and therapeutic efficacy.

3. Age-Specific Therapies
 Pediatric versus adult stroke: differing mechanisms and management priorities.
 Stroke in the elderly: frailty, comorbidities, and challenges in reperfusion therapies.
 Neuroplasticity, rehabilitation, and cognitive outcomes across age groups.

4. Translational and Therapeutic Perspectives
 Precision medicine and patient-tailored therapeutic approaches.
 Incorporation of anatomical and demographic variability into predictive models and trial designs.
 Future directions for personalized rehabilitation and secondary prevention.

This Research Topic will serve as a multidimensional platform highlighting how intrinsic variability among patients influences both disease course and therapeutic strategies in stroke. By integrating perspectives across neuroanatomy, endocrinology, geriatrics, imaging, and clinical practice, the collection aims to:

 Advance understanding of heterogeneity in stroke pathophysiology.
 Promote equity by addressing sex and age as determinants of care.
 Inspire more inclusive and representative clinical research.
 Translate individualized insights into improved patient outcomes.

This collection will be of interest to neurologists, neurosurgeons, neuroradiologists, stroke physicians, rehabilitation specialists, and basic scientists working on neurovascular biology. By attracting multidisciplinary contributions, it will foster a more nuanced understanding of diversity in stroke and accelerate the transition toward precision stroke medicine.

Topic editors

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).
